GRHD FOR CARS OF INCLINED ROADS.

SPECIFICATION forming part of Letters Patent No. 426,276, dated April 22, 1890.

Application filed February 17, 1890- Serial No. $10.704. (No model.)

T0 all whom it 11i/ty concern:

Be itknown that I, JACOB MILLER IsENBEEG, of Mines, in the county of Blair and State of Pennsylvania, have invented a new and Improved Grip for Cars of Inclined Roads, of which the following is a full, clear, and exact description.

My invention relates to an improvementl in grips adapted for use in connection with the cars of inclined roads, and has for its object to provide a device capable of attachment to any ear which will automatically act when the speed of the ear is increased, by reason of the breaking of a cable, for instance, to clamp the ties of the track, and thereby hold the car in a fixed position.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in both the views.

Figure 1 is a pla'n view of the bottom of the car, the body being removed; and Fig. 2 is a central vertical section illustrating the car upon the track and the claws as clamping a tie of the rails.

Upon two cross-bars 10, secured to the frame 11 of the bottom of the car between the car-axles, a governor A is journaled, which governor consists of a body-bar 12, in which two arms 13 are pivoted in such 1nanner that they extend through and from opposite sides of the bar, and the forward ends of said arms are connected by links 1i with a sleeve 15, held to slide upon the forward portion of the body-bar 12. Near the pivotal point of the arms 13 the body-bar 12 is threaded, and a nut 16 is screwed upon the said threaded surface, while between the contiguous faces of the nut and the sleeve 15 a spring 17 is coiled around the body-bar. Thus by screwing the nut 1G to or from the pivotal point of the arms 13 the governor may be regulated to act when the car travels faster than the predetermined speed.

Upon the forward journal of the body-bar 12 a post 18 is formed, upon which post a latch 19 is fulcrumed, the said latch at its forward extremity being provided with a suitable head, and the rear extremity of the latch is curved downward at an inclination in the direction of the rear, as illustrated at 20 in Fig. 2, the said downwardly-curved cx tremity of the latch being adapted for engagement by the forward end of the sleeve 15 of the governor.

At the upper or forward end of the car, preferably beneath the forward axle, a cradle B is pivoted in suitable hangers projected downward from the frame of the car. This cradle is ordinarily made to consist of two side bars 21, having their outer ornpper ends curved downward to a hook form, as illustrated at 22 in Fig. 2, the said side bars at or near their rear ends being connected by cross rods or bars 23, and upon the rear cross bar or rod a keeper 24 is securely fastened, consisting ordinarily of a fiat bar extending vertically upward and having a slot produced in the upper end for the admission of the head of the latch 19. The governor having been properly set, the cradle is carried to a horizontal position, so as to cause the hook extremities to be at an elevation above the ties and not interfere with the travel of the car. The cradle is retained in this position by the latch 19 engaging with the cradle-keeper 24.

A pawl 25 is pivoted or hinged to the forward portion of the frame of the car above each of the side pieces of the cradle, the said side pieces being provided with notches 2G to receive the pawl. In the event that a cable should break or other accident happen whereby the ear when drawn upward would run down the incline, as soon as the speed of the car increases the arms of the governor, approaching one another, will draw the sleeve 15 in the direction of the said arms, and as the sleeve is drawn inward by reason of its engagement with the downwardly-extending extremity of the latch the forward extremity of the latch is freed from the keeper 211, whereupon, the cradle being free and the hooked extremity of the cradle quite heavy, the said cradle drops by gravity until the hooks 22 thereof engage with one of the ties of the track, thus eifectually arresting the further progress of the car.

It will be understood that the governor is IOO driven from one of the axles of the car, preferably the rear aXle, and this is ordinarily accomplished by attaching to the axle a mitergear 27, which meshes With a pinion 28, attached to the body-bar l2 of the governor.

When the cradle is in contact With the ties of the road, the cradle is prevented from losing its grip upon the ties by the pawls 25 dropping downward and entering one of the notches. 26 in the side bars.

latch, substantially as shown and described.

2. In a railway-car, the combination, with a governor and a latch actuated by said governor, of a cradle pivoted at one end of the car and terminating in hooks or clawsand a keeper secured to the said cradle and adapted for engagement by the latch, substantially as shown and described.

3. The combination, with a governor anda latch operated by said governor, of a cradle adapted to be pivoted beneath a car, consisting of side bars terminating in a hook or claw and cross-bars uniting the side bars at their rear ends, and a keeper-bar attached to one of the cross-bars and adapted for engagement with the latch, substantially as shown and described, and for the purpose specified.

4. The combination, with the axle of a car and a governor driven by said axle, of alatch fulcrumed near the governor and adapted to be operated thereby, a cradle adapted to be pivoted beneath the car, consisting of side bars terminating in a hook or claw at one end and cross-bars uniting said side bars, and a keeper attached to one of the cross-bars of the cradle and adapted to be engaged by said latch, substantially as shown and described, and for the purpose specified.
